BUG: Auto-fill and auto-zoom feature doesn't work on HDMI after power cycle

Model: 42PFL5405H/12
SW: Q5521-0.140.27.0 (earlier as well)
Summary: Auto-fill and auto-zoom feature doesn't work on HDMI after power cycle.

Description: I use auto-fill picture format with my set-top-box connected to HDMI. However, when TV is powered off and powered back on, auto-fill (auto-zoom as well) feature doesn't work anymore on HDMI source (works on internal DVB-T). The only way how to make it work is to add fake device on another HDMI, switch to that fake source and then switch back. So every time I turn on my TV I have to switch to HDMI2 and then back to HDMI1. Is it possible to fix this bug in next SW release?

This is very annoying bug for me since I have bought Philips because of this feature.

I would like to mention that I'm very disappointed with local Philips support in Slovakia. I reported this bug and their reply was completely useless (...not all functions are supported on HDMI....bla bla bla...). I replied with request to forward this crystal-clear bug to R&D and they didn't answer anymore.

Dear user,

don't be afraid: even in Italy the Philips Support Center is not better than yours.

I have 32PFL5605H and i've this same problem. Function of auto-fill and auto zoom doesn't work. It to disturb watching when TV station to broadcast with letterbox around screen. I have to change it in STB.

I'm too lazy to translate all, but generally they are saing that it's not possible to use all functions on HDMI and other bullshit about HDCP keys incompatibility. At the end they suggest to set the format on STB to 4:3.
It seems like generic auto-reply email in case customer is complaining about anything regarding HDMI.

This is crystal clear BUG. More people in more countries should spam philips support about this. Maybe not all support people are so ignorant.

Thank you for your e.mail, very much appreciate that using the services and products of our company.
In the case when it receives from the STB TV as an external signal through the HDMI cable is not always possible
to fully exploit all the features of television, where all the functions of LCD TV. HDMI transmits
always information without changing the resolution, it means that if for example your STB sends the signal in the 16:9 format
to TV, HDMI cable, it sends no change in 16:9 format. In this case it is not possible to fully exploit
picture formats in the LCD TV because TV has already received a signal in some cases can additionally
process, to stretch the width. Also in this connection may not work item, Delta volume, balance
sound, EPG, MHP and some inne. LCD TV model 42PFL5405H/12 supports many functions only through
DVB-T. You can also encounter problems of incompatibility between certain functions of the STB to connect the
HDMI cable into the LCD TV, the incompatibility HDCP keys. In this case it is necessary to use certified
Cable HDMI CEC. Some STB allows connection to the TV by a cable YPbPr - Component whereby
can send a signal in high resolution. This cable allows you to send a signal even in the higher ranked resolution
if the HDMI cable, and additionally does not use HDCP keys. Some however, have the STB software
locked, bounded by a cable connection Component because it is impossible to convert
recordings, copies movies in high resolution, and thereby violate copyright producers of films.
In this case, transmission occurs when using Component cable to transfer only in size
PAL 720 x 576th We recommend you redundancy in your STB output video format in 4:3, 4:3 or widescreen,
in this case, the STB sends a signal to the partial provision for expansion using the picture format in LCD TV.

The support answer quoted above, hinting to some generic not-always-possibility, missed the point. In fact Auto Zoom feature on a digital cable decoder signal fed through HDMI is not only possible - it is actually implemented and working. The only trouble is, it STOPS working every time TV power is turned off and on. After that it has to be reset again by user’s workaround action described below. It obviously is a firmware bug.

As Auto Zoom was the sole reason why I chose to buy Philips TV, not Samsung, I would be very disappointed if you dear Philips guys reading this forum do not fix this bug.

Bug description:
Auto Zoom works properly all the time on analog cable TV signal (through concentric). I didn’t check it on DVB-T source. When a digital HD cable decoder (through HDMI 1) is freshly set up, it works just as well (with adjustment delay up to 15 secs). But it works only until the TV power is turned off (standby). When the TV is powered back again, it no longer works properly: it can still show undistorted 4:3 and 16:9 formats, but becomes unable to zoom in letterboxed picture formats.

Workarounds:
After power on, the Auto Zoom can be reset to work again by one of the following actions (to be repeated after every power cycle):

Switch to another digital device connected through HDMI 2 (tested on a BD player). After this device powers up and displays its content ("no disc" screen is sufficient), switch the signal source back to digital TV decoder on HDMI 1.

Delete the digital decoder from the menu and add it as a new device again.

Rename the digital decoder device to a custom name (I didn’t have a heart to repeat it again to make sure).
